Preventive measures against degradation of the latest potato varieties

Potato degradation is a common phenomenon in production, and the direct manifestation of degradation is abnormal plant growth, small tubers and a substantial decline in yield, which seriously affects the income of farmers. The main reason for potato degradation is to plant a variety all the year round, resulting in the gradual accumulation of virus, so how to prevent the degradation of potato varieties? Come and have a look with the editor.

1. Select varieties with strong disease resistance.

Different potato varieties have different resistance to virus disease. some varieties with strong disease resistance can be planted continuously for three years and can still maintain high yield, but some varieties will have a significant reduction in yield after two years. Therefore, it is very important to select varieties with strong disease resistance. at the same time, we should pay attention to selecting the remaining seeds compared with potato products when planting, so that we can appropriately prolong the high-yield life, and pay attention to the disinfection and sterilization of soil, which can also increase the high-yield life accordingly and delay the degradation of varieties.

2. Change varieties frequently

The best way to avoid the degradation of potato varieties is to change varieties frequently. At this time, the most effective way to prevent variety degradation is that when many friends buy seeds, manufacturers often advise them to buy different varieties. But some friends think that they are deceiving them and think that the cost of changing seeds is worth compared to the loss caused by production. This is a wrong idea. Varieties must be changed frequently in production, preferably once every 1-2 years.

3. Cultivate non-toxic varieties.

Through the study, it is found that the parts with strong meristematic ability such as root tip and stem tip of potato do not contain virus, and the probability of virus infection is very low, so this part of potato can be used for virus-free yield. then use the seedlings cultivated by tissue for production, such seedlings will not carry germs, this is non-toxic seedlings.

4. Control the disease.

Virus infection is mainly due to poor control of disease in the field, resulting in the accumulation of virus diseases more and more year by year, and the best way to reduce variety degradation is to control the incidence in the field. Especially for the infection of the virus, it is found that the infected plants are pulled out in time, burned or buried in the field, and then sprayed or treated with lime to avoid the spread of the disease, if there are signs of spread, comprehensive drug spraying should be carried out, and the sooner the better.
